Skills

Professional skills for nasty bugs, hard decisions and software that needs to work.

I build them from problems I meet in engineering, product and security work. They give capable models the missing professional habits: investigate before guessing, resolve the real decision, respect authority and prove that the result works.

Choose the right one

The cause is unknown or the bug keeps coming back: use Dig Deeper.
Diagnosis needs tools, reproduction or controlled experiments: use Dig Deeper Probe.
The request hides a consequential decision: use Smart Shot.
The work is bounded and reversible: use Fast Shot.
You want a small runnable tool, script, query or demo: use SFLO Quick.
A skill has become expensive to load: use Skill Compressor.

Dig Deeper

Dig Deeper is great for nasty, deep bug diagnosis. It uses logs, system state, documentation, code and other available evidence. Probe mode can install tools, reproduce failures and run controlled experiments when observation is not enough.

Smart Shot

Smart Shot figures out what a consequential request should mean, brings in the right specialists, does the authorized work and independently tests the result.

Fast Shot

Fast Shot makes a bounded, reversible decision or change with enough evidence to trust it, without paying for a specialist panel.

SFLO Quick

SFLO Quick turns a small software idea into something runnable and checked. It is for scripts, SQL, data work, demos and personal tools that may need several implementation passes.

Skill Compressor

Skill Compressor makes a skill cheaper to load without breaking when it activates or how it behaves.

What makes these different

They come from real engineering, product and security work.
Evidence stays separate from a persuasive story.
The agent knows what it may inspect, change and ship.
Completion is tested. A confident claim is not evidence.
More instructions survive only when they improve measured behaviour.
